Abstract:
Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic resonance, magnetization patterns can be made visible. When using increasingly intense pulses, however, the magnetization image fades away. The mechanism responsible for this loss in resonant magnetic scattering intensity has now been clarified.

Who stole the light? Self-induced ultrafast demagnetization limits the amount of light diffracted from magnetic samples at soft x-ray energies


Berlin, Germany | Posted on September 18th, 2020

Just as in flashlight photography, short yet intense flashes of x-rays allow to record images or x-ray diffraction patterns which “freeze” motion that is slower than the duration of the x-ray pulse. The advantage of x-rays over visible light is that nanometer scale objects can be discerned due to the short wavelength of x-rays. Furthermore, if the wavelength of the x-rays is tuned corresponding to particular energies for electronic transitions, one can obtain unique contrast, allowing for example to make the magnetization of different domains within a material visible. The fraction of x-rays scattered from a magnetic domain pattern, however, decreases when the x-ray intensity in the pulse is increased. While this effect had been observed already in the very first images of magnetic domains recorded at a free electron x-ray laser in 2012, a variety of different explanations had been put forward to explain this loss in scattered x-ray intensity.

A team of researchers from MBI Berlin, together with colleagues from Italy and France, has now precisely recorded the dependence of the resonant magnetic scattering intensity as a function of the x-ray intensity incident per unit area ( the “fluence”) on a ferromagnetic domain sample. Via integration of a device to detect the intensity of every single shot hitting the actual sample area, they were able record the scattering intensity over three orders of magnitude in fluence with unprecedented precision, in spite of the intrinsic shot-to-shot variations of the x-ray beam hitting the tiny samples. The experiments with soft x-rays were carried out at the FERMI free-electron x-ray laser in Trieste, Italy.

Magnetization is a property directly coupled to the electrons of a material, which make up the magnetic moment via their spin and orbital motion. For their experiments, the researchers used patterns of ferromagnetic domains forming in cobalt-containing multilayers, a prototypical material often used in magnetic scattering experiments at x-ray lasers. In the interaction with x-rays, the population of electrons is disturbed and energy levels can be altered. Both effects could lead to a reduction in scattering, either through a transient reduction of the actual magnetization in the material due to the reshuffling of electrons with different spin, or by not being able to detect the magnetization anymore because of the shift in the energy levels. Furthermore, it has been debated whether the onset of stimulated emission at high x-ray fluences administered during a pulse of about 100 femtoseconds duration can be responsible for the loss in scattering intensity. The mechanism in the latter case is due to the fact that in stimulated emission, the direction of an emitted photon is copied from the incident photon. As a result, the emitted x-ray photon would not contribute to the beam scattered away from the original direction, as sketched in Fig.1.

In the results presented in the journal Physical Review Letters, the researchers show that while the loss in magnetic scattering in resonance with the Co 2p core levels has been attributed to stimulated emission in the past, for scattering in resonance with the shallower Co 3p core levels this process is not significant. The experimental data over the entire fluence range is well described by simply considering the actual demagnetization occurring within each magnetic domain, which the MBI researchers had previously characterized with laser-based experiments. Given the short lifetime of the Co 3p core levels of about a quarter femtosecond which is dominated by Auger decay, it is likely that the hot electrons generated by the Auger cascade in concert with subsequent electron scattering events lead to a reshuffling of spin up and spin down electrons transiently quenching the magnetization. As this reduced magnetization manifests itself already within the duration of the x-ray pulses used (70 and 120 femtosecond) and persists for a much longer time, the latter part of the x-ray pulse interacts with a domain pattern where the magnetization has actually faded away. This is in line with the observation that less reduction of the magnetic scattering is observed when hitting the magnetic sample with the same number of x-ray photons within a shorter pulse duration (Fig.2). In contrast, if stimulated emission were the dominant mechanism, the opposite behavior would be expected.

Beyond clarifying the mechanism at work, the findings have important ramifications for future single shot experiments on magnetic materials at free electron x-ray lasers. Similar to the situation in structural biology, where imaging of protein molecules by intense x-ray laser pulses can be impeded by the destruction of the molecule during the pulse, researchers investigating magnetic nanostructures also have to choose the fluence and pulse duration wisely in their experiments. With the fluence dependence of resonant magnetic scattering mapped out, researchers at x-ray lasers now have a guideline to design their future experiments accordingly.

The Process of Reaction Injection Molding

Avatar

Published

on

This guide to the process of reaction injection molding will help you determine if the popular and advantageous molding method is suited to your application.

Reaction injection molding (RIM) is a type of popular part molding process for producing large, complex parts in lower volumes. This unique process offers several benefits, such as lower tooling costs, sophisticated aesthetics, and unparalleled design freedom. If you are interested in utilizing RIM as your part production method, continue reading to learn more about the process of reaction injection molding.

Liquid Polymers Are Mixed Together

The process of reaction injection molding begins by mixing two liquid polymers together. The liquid polymers used in the process are known as polyol and isocyanate. These polymers are dispensed from their storage tanks into a multi-stream mixhead by high-pressure industrial pumps and then recirculated back into their storage tanks in a continuous loop.

The Mixture Is Injected Into an Aluminum Tool

Once blended together, the polyol and isocyanate create a low-viscosity mixture. This mixture is then injected into a heated mold. Because the mixture has a low viscosity, it does not require extremely high temperatures or pressures in order to get the material to fit the tool.

As such, the mold is typically made from low-cost aluminum rather than expensive steel which is required for many other molding processes such as injection molding. Thus, opting for RIM over other methods can greatly lower tooling costs and is often highly economically beneficial when creating parts in smaller production volumes.

The Chemical Reaction Takes Place

After the polymer mixture is injected into the aluminum mold, a heat-generating chemical reaction will take place. The reaction will cause the mixture to expand and fill the space of the mold. Upon doing so, the material will quickly harden. Curing times for reaction injection molded parts can range anywhere from a few seconds to several minutes, depending on a variety of factors such as the part’s size, wall thickness, and geometry.

The Finished Part Is Removed From the Tool

Once the polymer mixture hardens inside of the mold, it is ready to be removed. RIM generally has very short demolding times in comparison to other processes. Once the part is demolded, the reaction injection molding process can immediately begin again.

Abstract:
Optical nanoantennas can convert propagating light to local fields. The local-field responses can be engineered to exhibit nontrivial features in spatial, spectral and temporal domains. Local-field interferences play a key role in the engineering of the local-field responses. By controlling the local-field interferences, researchers have demonstrated local-field responses with various spatial distributions, spectral dispersions and temporal dynamics. Different degrees of freedom of the excitation light have been used to control the local-field interferences, such as the polarization, the beam shape and beam position, and the incidence direction. Despite the remarkable progress, achieving fully controllable local-field interferences remains a major challenge. A fully controllable local-field interference should be controllable between a constructive interference and a complete destructive interference. This would bring unprecedented benefit for the engineering of the local-field responses.

Turning a hot spot into a cold spot: Fano-shaped local-field responses probed by a quantum dot


Changchun, China | Posted on October 9th, 2020

In a new paper published in Light Science & Application, a team of scientists from China, led by Professor Sailing He from Zhejiang University and Professor Jianwei Tang from Huazhong University of Science and Technology, have experimentally demonstrated that based on a fully controllable local-field interference designed in the nanogap of a nanoantenna, a local-field hot spot can be turned into a cold spot, and the spectral dispersion of the local-field response can exhibit dynamically tunable Fano lineshapes with nearly vanishing Fano dips. By simply controlling the excitation polarization, the Fano asymmetry parameter q can be tuned from negative to positive values, and correspondingly, the Fano dip can be tuned across a broad wavelength range. At the Fano dips, the local-field intensity is strongly suppressed by up to ~50-fold.

The nanoantenna is an asymmetric dimer of colloidal gold nanorods, with a nanogap between the nanorods. The local-field response in the nanogap has the following features: First, local field can be excited by both orthogonal polarizations; Second, the local-field polarization has a negligible dependence on the excitation polarization; Third, the local-field response is resonant for one excitation polarization, but nonresonant for the orthogonal excitation polarization. The first two features make the local-field interferences fully controllable. The third feature further enables Fano-shaped local-field responses.

For experimental study of the local-field responses, it is crucial to probe the local fields at specified spatial and spectral positions. The scientists use a single quantum dot as a tiny sensors to probe the local-field spectrum in the nanogap of the nanoantenna. When the quantum dot is placed in the local field, it is excited by the local field, and its photoluminescence intensity can reveal the local-field response through comparison with its photoluminescence intensity excited directly by the incident light.

Superb fabrication technique is needed to fabricate such a tiny nanoantenna and put the tiny quantum dot sensor into the nanogap. The scientists use the sharp tip of an atomic force microscope (AFM) to do this job, pushing nanoparticles together on a glass substrate.

The scientists summarized the relevance of their work:

“Turning a local-field hot spot into a cold spot significantly expands the dynamic range for local-field engineering. The demonstrated low-background and dynamically tuneable Fano-shaped local-field responses can contribute as design elements to the toolbox for spatial, spectral and temporal local-field engineering.”

“More importantly, the low background and high tunability of the Fano lineshapes indicate that local-field interferences can be made fully controllable. Since the local-field interferences play a key role in the spatial, spectral and temporal engineering of the local-field responses, this encouraging conclusion may further inspire diverse designs of local-field responses with novel spatial distributions, spectral dispersions and temporal dynamics, which may find application in nanoscopy, spectroscopy, nano-optical quantum control and nanolithography.”

Abstract:
The key to promoting the hydrogen economy represented by hydrogen vehicles is to produce hydrogen for electricity generation at an affordable price. Hydrogen production methods include capturing by-product hydrogen, reforming fossil fuel, and electrolyzing water. Water electrolysis in particular is an eco-friendly method of producing hydrogen, in which the use of a catalyst is the most important factor in determining the efficiency and price competitiveness. However, water electrolysis devices require a platinum (Pt) catalyst, which exhibits unparalleled performance when it comes to speeding up the hydrogen generation reaction and enhancing long-term durability but is high in cost, making it less competitive compared to other methods price-wise.

Development of cost-efficient electrocatalyst for hydrogen production: Development of a highly efficient and durable electrocatalyst for water electrolysis that will lead to cost-efficient hydrogen production. Trace amounts of titanium doping on low-cost molybdenum phosphide resu


Sejong, Korea | Posted on October 9th, 2020

There are water electrolysis devices that vary in terms of the electrolyte that dissolves in water and allows current to flow. A device that uses a proton exchange membrane (PEM), for instance, exhibits a high rate of hydrogen generation reaction even with the use of a catalyst made of a transition metal instead of an expensive Pt-based catalyst. For this reason, there has been a great deal of research on the technology for commercialization purposes. While research has been focused on achieving high reaction activity, research on increasing the durability of transition metals that easily corrode in an electrochemical environment has been relatively neglected.

The Korea Institute of Science and Technology (KIST) announced that a team headed by Dr. Sung-Jong Yoo from the Center for Hydrogen-Fuel Cell Research developed a catalyst made of a transition metal with long-term stability that could improve hydrogen production efficiency without the use of platinum by overcoming the durability issue of non-platinum catalysts.

The research team injected a small amount of titanium (Ti) into molybdenum phosphide (MoP), a low-cost transition metal, through a spray pyrolysis process. Because it is inexpensive and relatively easy to handle, molybdenum is used as a catalyst for energy conversion and storage devices, but its weakness includes the fact that it corrodes easily as it is vulnerable to oxidation.

In the case of the catalyst developed by the research team at KIST, it was found that the electronic structure of each material became completely restructured during the synthesis process, and it resulted in the same level of hydrogen evolution reaction (HER) activity as the platinum catalyst. The changes in the electronic structure addressed the issue of high corrosiveness, thereby improving durability by 26 times compared to existing transition metal-based catalysts. This is expected to greatly accelerate the commercialization of non-platinum catalysts.

Dr. Yoo of KIST said, “This study is significant in that it improved the stability of a transition metal catalyst-based water electrolysis system, which had been its biggest limitation. I hope that this study, which boosted the hydrogen evolution reaction efficiency of the transition metal catalyst to the level of platinum catalysts and at the same time improved the stability will contribute to earlier commercialization of eco-friendly hydrogen energy production technology.”

This study was carried out with a grant from the Ministry of Science and ICT (MSIT), as part of the Institutional R&D Program of KIST, the Technical Development Program for Responding to Climate Change, and the Global Frontier Multi-Scale Energy System Research Program. It was published in the latest edition of Nano Energy (IF: 16.602, Top 4.299% in the field of JCR), a leading international journal in the area of energy and nanotechnology.
